Over the past 20 years the molecular-scale electronics community has studied junctions comprised of a multitude of different molecules, generating an enormous amount of conductance data. The Molecular Junction Database (MJD) Project aims to link molecular structures to published transport studies and other key metrics. The goal of this effort is to provide a comprehensive, searchable index that allows relevant studies to be easily identified, and to facilitate opportunities for further data analysis. The MJD was established in 2020, and is curated by the Inkpen Lab at the University of Southern California.
